INTERLOCKING HOOK FOR WIRE FABRIC.

To all whom it may concern:

Be it known that I, GARY B. SMITH, a citizen of the United States, residing at Minneapolis, in the county of Hennepin and State of Minnesota, have invented a new and useful Interlocking' Hook for Wire Fabric, of which the following' is a specification.

This invention has relation to interlocking hooks for wire fabric and it consists in the novel construction and arrangement of parts hereinafter shown and described.

The object of the invention is to provide a hook especially adapted to be used for connecting the cables of a wire fabric together, whereby the said cables may move laterally with relation to each other and still be maintained in approximate relative relations, thus preventing the fabric from warping or drawing out of shape.

With the above object in view the hook is formed from a single piece of wire which is bent, at its ends, into the form of a loop shank about the strands of the cables, and which, at its intermediate portion, is formed into a hooked head, which engages an adjacent cable, and also straddles the shank.

portion of the hook mounted upon the said adjacent cable in such manner that the cables may have relative movement laterally. By providing such a structure a fabric may be applied to the frame of a couch or a bed irrespective of the distance between the perforations or securing devices upon the frame; for, should the perforations or the securing devices be closer together than the length of the hook, one hook may telescope with the other or move longitudinally along the same, whereby the cables constituting the fabric may assume positions at distances from each other equal to the distances between the said perforations or securing devices upon the frame of the bed or couch.

In the accompanying drawings Figure l is a plan view of a section of the fabric equipped with the hook. Fig. 2 is a perspective View of adjacent cables of the fabric, showing the hook applied thereto. Fig. 3 is a plan view of a modified form of cable which may be employed in the fabric. Fig. 4 is a plan view of still another modified form of cable, which may be employed in the fabric. Fig. 5 is a perspective view, showing the hook applied to the form of fabric as shown in Fig. 4. Fig. 6 is a side Specication of Letters Patent.

elevation of the hook, showing the same applied to the form of fabric as illustratedin Fi 5.

is shown in Fig. l of the drawings, the cables l consist of the strands 2, which are helically twisted together throughout the length of the cables, and to the ends of which are attached the springs 3. The said springs are of usual construction and are adapted to be secured to perforations or securing devices upon the frame of the couch or bed (not shown).

In the form of cable as illustrated in Fig. 3, but a single strand is used, the ends of which are spliced together as at 4, and the loops 5 are formed for engagement with springs similar to those shown at 3 in Fig. l.

In the form of fabric, as illustrated in Figs. 4 and 5 of the drawings, the strands are helically twisted together as at 6, and are substantially parallel with each other at intervening portions as at 7. The hook used in connection with the cables of the fabric is formed from a single piece of wire, bent, at its ends, into the form of a hook or shank 8 about the strands of the cables upon which t-he said hook is mounted. The said shank S forms one extremity of t-he hook proper, while its other extremity is formed into the head 9, which straddles the shank of the hook upon the next adjacent cable, and also engages the last said cable. The space betweenl the side portions of the head 9 is sufficient to permit the head portion of one hook to pass freely along the shank portion of the adjacent hook which is straddled, and thus,

vwhen the fabric is applied to the frame of a bed or couch, the cables of which the fabric is composed may assume distances from each other equal to the distances between the perforations or securing devices upon the frame of the bed or couch.

As illustrated in Figs. l and 2 of the drawings, the shank portion 8 of the hook may be clenched or compressed about the helically twisted strands of the cable, or, as illustrated in Figs. 4, 5 and 6 of the drawings, the said shank portion may be compressed or clenched about the approximately parallel portion 7 of the strands of the cable. By clenching the shank portion 8 about the parallel portions of the strands of the cables, the said hook cannot rotate about the cable as an axis, and the relative lateral movement of the adjacent cables must occur Within the head portion 9 of the hook, and not at the shank portion thereof.

Having described my invention, what I claim as new, and desire to secure by Letters Patent, is

l. A fabric comprising adjacent cables, a hook fixed at its shank to each cable,y each hook having a head which engages the ad jacent cable, and which straddles the shank of the hook mounted upon the adjacent cable.

2. A fabric comprising adjacent cables having strands in approximate parallel relation, a hook mounted upon each cable andk having a shank end clenched about the par- 15 allel strands of the cable7 each hook having a o head which engages the adjacent cable and Straddles the shank of the hook mounted upon the said adjacent cable.l Y

In testimony that I claim the foregoing as 20 my own, I have hereto aixed my signature in the presence of two Witnesses.
